Abstract

In this paper we present a simple and efficient numerical platform built with the purpose to contribute in the analysis of the intermodulation phenomenon. This effect appears when we need to measure many modulating signals patterns in complex digital 8-VSB and COFDM systems. This approach has direct application in the study of a wide class of RF power amplifier.
